What has surprised me is how shock absorbent they are. When I wore a different set of sneaks (ok, I admit, I grabbed the pair with the holes- I told myself I'd toss them, but keep putting it off), I immediately noticed a difference.
So, I do really like my new sneakers, though they do take some getting used to. For instance, because the bottom curves, taking stairs quickly would be a really bad idea.
Now I just have to figure out how to survive these 90 degree days in jeans, because sneakers and Capri pants look plain odd, and none of my shorts fit yet (and I haven't found any in the stores I like, darn short-short fashions).
